OIL BURNER.

Application led March 28, 1924. Serial No. 702,162.

To all whom it mag/"concern:

Be it known that I, EDISONM. SMITH, a

resident of West Hartford, county of Hartford, and State of Connecticut, have invent ed certain new and useful Improvements in Oil Burners, of which the following is a specification.

My invention relatesI tov the class of oil burners more especially adapted for use in furnaces, stoves and other heating appliances, and an object of my invention, among others, is to provide an oil burner that will be simple in construction and particularly ecient in operation.

, One form of burner embodying my invention and in the construction and use of which the objects herein set out, as well as others, may be attained, is illustratedl in the accompanying drawings, in which# Figure 1 is a view in central vertical section through an oil burner embodying my invention. i

Figure 2 is a view in cross section on a plane denoted by the dotted line 22 of Figure 1.

Figure 3 is a view in side elevation of the` upperjpart of my improved burner.

In the accompanying drawings" the nu-v meral v5 indicates a base plate, in the form of the device herein shown such plate being located in the bottom of the fire pot of `a. furnace .of ordinary construction. A rojectioni extends downwardly from the-p ate andhas a chamber -7'with which an air Inlet v8 communicates. Y I

A rotatable sleeve-v9 fis' mounted in the chamber v 7 extending therethrough this sleeve being supported at its lower end upon bearings :10 in the projection Gand at upperV end b bearings'111.m'ountedan acover 12. These arings may be of any of the well known types. of anti-friction bearin a propeller 14 is secured to the sleeve 9, the bladesf of the propeller being located opposite the passages 13 so that air forced through the inlet 8 into the chamber 7, being lunder pressure, will effect rotation of the turbineand consequently of the sleeve 9.

Y A- burner 15is secured t( the turbine and -s gbustion purposes to the burner. for supporting'thrust and radial loads. `Air passages 13 extend through the cover'12 and .cated in the wall of the cover 12 an sleeve to rotate with them, this burnervpreff erably having wallstapering from allesser diameter to. a greater diameter at the to so that oil su plied within the burner wi under the action of centrifugal forces, flow along the walls to the upper edge of" said4 burner. An oil inlet pipe 16 is connected' and is ex- Y to the lower end of the projection 6 tended u wardly' to plrovide an oil supply pi 17 exten ing throng the sleeve9 and intoft e burner 15. Outlets1 18 extend radially from the supply pipe and within the burner, these outlets being preferably inthe form of short tubes curved downwardl toward the bottom of the chamber in t e burner. A cap v19 is secured to a cap adjusting screw 20 screw threaded into the end of the pipe 17 f for the purpose of adjusting the size ofthe burner mouth between the edges of the burner and said cap.

' The base plate 5 is spa/ced from walls 21 i of the furnace a distance imposed 4by "con-` ditions and requirements, this space, however, usually not being sutlicient to supply an excessive amount of air in addition to that that flows throughthe passages 13 to the burner and I, therefore provide means for completing the supply of air, such means being adjustable to regulate the suppl.

l This consists of a. damper ring 22 surroun ing the cover 12 and resting upon the base 5.- This cover 12 is secured to the base and. said damper ring is mountedl for adjustable. rotary movement' around. the cover, said ringl `:find-'base being provided with passa es .23-

24 for. air from the lower side of t e plate .5 to the vupperside thereof.

1 This construction enables the openin comprising the passages 23-24 to be read' y ad'ustable to such'size as to supply just the ulljcient amount of air required for com- -The air passing in at the inlet 84 is also sleeve is rotate A This difusing ably adjustable upon the cover for the purpose of varying the size of the air ports 25 and 26 as may be desired to further regulate the amount of air to be supplied to the burner. Y

A diffusing plate 28 is mounted on posts 29 extending upwardly from the cover 12, this diffusing plate having perforations 30 for the passage of air from below the plate to the combustion chamber about the burner and above the plate. This plate is of dishshape with its concave side opening upwardly, and it is adjustably mounted on the posts 29 as by means of adjusting collars 31 fitting the screw threaded upper ends of said posts. plate is for the purpose of spreading the air over a comparatively wide area to lprevent such air' from passing up-l wardly adjacent to the burner 15 in a concentrated volume. l

A space 32 is left between the supply pipe 17 and the sleeve 9 for the purpose of permitting outflow of undesirable accumulation of oil in the burner '15, such oil flowing into a discharge chamber 33 and therefrom through a discharge tube 34 to any suitable place of deposit.

In accordance with the provisions of the patent statutes I have described the principles of operation of vvmy invention, together .with the device which I now consider to represent the best embodiment thereof; 'butl I desire to have it understood that the device shown is only illustrative and that the iiivention ma. be carried out by other means `and applic to uses other than those above set out. f

I .claim- `1. An oil burner comprising a, base with an air inlet chamber therein andan air in- `let opening to said chamber, a sleeve rotatably mounted in said chamber, means for ro'- tating said sleeve, a burner connected with said sleeve to be rotated tliereby,`a fuel supply pipe extending through said sleeve a'id spaced therefrom to receive excess oil from said burner, and an outlet from said space.

2. An oil burner .comprising a base with an air inlet chamber therein and an air inlet opening to said chamber, a stationary cover i for said chamber, said cover having air passages communicating with said chamber, a

means for supplying'fuel to said burner, and

a perforated diusing plate surrounding said burner underneath its mouth to diffuse air currents flowing therethrough.

5.
